Abstract

Electric power amplifier with several power amplifier components, especially power transistors arranged as emitter followers, which are mutually allocated in pairs complementarily in a push-pull B operative circuit, and with one or more bias voltage sources coupled to the input circuit of the pair of amplifier components to generate a constant static current flowing through the power amplifier components, with a regulator connected to the power amplifier components which controls the bias current source(s) to keep the static current constant.
